标准范围

ISO 3960:2007规定了一种用目视终点检测碘量法测定动植物油脂过氧化值的方法。过氧化值是以过氧化物（尤其是氢过氧化物）的形式与油或脂肪化学结合的氧气量的量度。该方法适用于每千克活性氧过氧化值为0-30 meq（毫当量）的所有动植物脂肪和油、脂肪酸及其混合物。它也适用于不同水分含量的人造黄油和脂肪酱。该方法不适用于乳脂，也不适用于卵磷脂。

ISO 3960:2007 specifies a method for the iodometric determination of the peroxide value of animal and vegetable fats and oils with a visual endpoint detection. The peroxide value is a measure of the amount of oxygen chemically bound to an oil or fat as peroxides, particularly hydroperoxides.The method is applicable to all animal and vegetable fats and oils, fatty acids and their mixtures with peroxide values from 0 meq to 30 meq (milliequivalents) of active oxygen per kilogram. It is also applicable to margarines and fat spreads with varying water content. The method is not suitable for milk fats and is not applicable to lecithins.
